The aim of the present study is to depict a combined vertical and horizontal ridge augmentation with autogenous bone block graft and guided bone regeneration in the anterior of the mandible to increase vertical and horizontal bone for implants placement. A 46-year-old male Hispanic patient referred with a complaint of missing lower anterior teeth. Medical history showed only an allergy to Prochlorperazine. Radiographic examination showed a thin horizontal bone width and loss of vertical height at anterior of mandible.Clinical examination revealed good oral hygiene with poor prognosis of teeth #32 and #42. The proposed treatment was to a traumatically extract teeth #32 and #42 and augments the area with a 2 block grafts harvested from the symphysis of the mandible (Chin block) and after bone block healing implants will be placed to restore the lower anterior area. To conclude, block bone graft is a gold standard procedure to gain vertical and horizontal augmentation of alveolar ridge in the anterior of the mandible.
